Driving along and without warning drive seems to have quit. No matter what gear no go. On Jack stands all wheels and drive lines rotate freely. No noise, no disconnect. Could this be an electrical issue? Fuse (F102=TCM)? I seen this topic before but never resolved. Thx. One note, for about a day before the shifting seemed to be stiffer, shifting at lower rpm and gas mileage went down? Hmm?

Have you checked the codes at all, or recently serviced the trans?

No codes- Inspected and cleaned physical and electrical components

No codes or engine light- Inspected and cleaned physical elements axles, drivelines etc. Also electrical components, the fuse panel in glove compartment was rusted.
Automatic transmission is now working although I can point to what fixed it. May electrical and computer like systems affect how the transmission works and shifts including braking and traction.

There is a transmission module that may have been affected but the gear light with the ! would have shown on the dash. 77'911 meant those codes and other modules that can be read with the proper software not just engine codes.
